摘要:An investigation was performed to evaluate objectively observer's ability to find lung nodules on compressed spiral computerized tomographic (CT) images of the chest. A set of 80 images from 13 patients served as backdrops. One simulated nodule of either 3.0, 3.4, 4.0, or 5.0 mm ...

摘要:... We have evaluated the performance tradeoffs for different block sizes and their effects on the image quality of chest radiographs. The results showed that there is no significant difference in root-mean-square error nor in power spectra between different block sizes for visua...
